media: iris: implement set properties to firmware during streamon

During the stream on operation, set some mandatory properties on the
firmware to start a session. Set all v4l2 properties, which are set by
the client, on to firmware, which is prepared with the dependency graph.

+ * QC08C:
+ * Compressed Macro-tile format for NV12.
+ * Contains 4 planes in the following order -
+ * (A) Y_Meta_Plane
+ * (B) Y_UBWC_Plane
+ * (C) UV_Meta_Plane
+ * (D) UV_UBWC_Plane
+ *
+ * Y_Meta_Plane consists of meta information to decode compressed
+ * tile data in Y_UBWC_Plane.
+ * Y_UBWC_Plane consists of Y data in compressed macro-tile format.
+ * UBWC decoder block will use the Y_Meta_Plane data together with
+ * Y_UBWC_Plane data to produce loss-less uncompressed 8 bit Y samples.
+ *
+ * UV_Meta_Plane consists of meta information to decode compressed
+ * tile data in UV_UBWC_Plane.
+ * UV_UBWC_Plane consists of UV data in compressed macro-tile format.
+ * UBWC decoder block will use UV_Meta_Plane data together with
+ * UV_UBWC_Plane data to produce loss-less uncompressed 8 bit 2x2
+ * subsampled color difference samples.
+ *
+ * Each tile in Y_UBWC_Plane/UV_UBWC_Plane is independently decodable
+ * and randomly accessible. There is no dependency between tiles.
